China's assertive response to the tug of war with Japan over the disputed Diaoyu Islands has strong domestic support. Nationalistic sentiments have been surging. Memories of Japanese atrocities done to the Chinese people have been kept fresh through the mass and social media.
The Diaoyu Islands are a group of uninhabited islands located roughly due east of mainland China, northeast of Taiwan, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands. They are currently controlled by Japan, which calls them Senkaku Islands. Both China and Taiwan claim sovereignty over the islands.
